Variation resulting from the appearance of mutations is called variation through mutation while that conditioned by subsequent recombination of genes as a result of interbreeding is called variation through recombination.roup variation includes the differences among aggregates of any rankâfrom differences among small groups of individuals within a population to differences among the kingdoms of living nature (animals and plants).
